just pulled my first board out of the press, everything went good... except for the top sheet. We are using iso sport nylon (sublimated), where did we go wrong? not enough resin? heat was off? ( we heat from bottom only). is there any special bonding pretreatment need? how much does it not being clean actually affect it? I think we were pretty cleaned up (maybe not enough). any tips words of wisdom would be rad!!

thanks

Is the back of the topsheet a felty material like the pbt or is it just an abraded surface?
you may have needed to flame treat if it was just an abraded surface but not sure how the ntlon material would like this. The material should be as clean as possible. How bad was the delam? Pics?

wish i took some pics, but were talking 50% didnt bond properly if was f*#ked. it kinda threw me off a bit cuz the rest of it went pretty good.

Where did u have this sublimated at miller studio?

ya it was miller that did it

i guess if all else ill call them but i was hoping to press again tomorrow if i got any good feedback

Are you sure you had the epoxy/hardener mix correct? if you have a short pot life and are mixing in multiple batches, and screwed up the last batch, then that might explain it.

I got burned on this a while back after getting lazy and mixing by volume instead of weight. Now I'm back to weighing the epoxy and hardener mix to the gram.

I press up another one, flamed and cleaned better, changed the heat a little and everything went great. the nylon looks and works great so far.

so it is okay to flame treat the sublimated material from miller studio. i was going to post something about it because i was not totally sure

vince says its flame treated but that can wear off as we know. I just did a test on this material an the half I flame treated bonded better than the other half that came straight from the roll.
Its thin, so fast passes with the torch.
